A. A jar test can quickly determine physical compatibility. The process of conducting jar test is given below:
STEP 1: Add one pint of water to a glass jar with a lid. (Use the same water source that will go in the tank).
STEP 2: Check spray water pH and adjust if necessary. Often, the pesticide label will give the optimal pH range for best results.
STEP 3: Add the pesticides to the jar you plan to use one at a time and shake vigorously after each addition.
STEP 4: After all products have been added, shake again, let the solution stand for 15 minutes and then shake one last time and observe the results.
Results: Jar is cool to the touch, and mixture is smooth. Then it is compatible mixture.
